Hi Andrea,<br><br>Did you manage to access the VM through ssh? or are you using VNC?<br><br>If you can't ping anything from the VM, maybe you could try adding other VMs to that private network and check if they see each other.<br>
Or just configure the VM template to attach a network interface to the public network.<br><br>Regards,<br><br clear="all">Carlos Martín, Cloud Technology Engineer/Researcher<br>DSA Research Group: web <a href="http://dsa-research.org" target="_blank">http://dsa-research.org</a> and blog <a href="http://blog.dsa-research.org" target="_blank">http://blog.dsa-research.org</a><br>

Hi all,<br>
<br>
unfortunately also running the fsck on the .img didn't solve the
problem. Here my situation:<br>
<br>
- 1 x frontend: ubuntu 10.04 - KVM - NFS<br>
- 1 x cluster node: ubuntu 10.04 - KVM - NFS<br>
<br>
A ttylinux VM has been started correctly on the worker node. From the
front end:<br>
# onevm list<br>
ID USER NAME STAT CPU MEM HOSTNAME TIME<br>
21 oneadmin ttylinux runn 0 65536 <a href="http://grids21.eng.it" target="_blank">grids21.eng.it</a> 00 00:10:22<br>
<br>
# onevnet list<br>
ID USER NAME TYPE BRIDGE #LEASES<br>
8 oneadmin public Ranged br0 0<br>
9 oneadmin private Fixed br0 1<br>
<br>
<br>
The ttylinux VM shows this:<br>
# ifconfig <br>
eth0 ..... inet address 192.168.0.6 ...<br>
<br>
but I cannot ping anything from this VM<br>
<br>
<br>
To help the investigation, here the bctrl show command on the cluester
node<br>
$ brctl show<br>
bridge name bridge id STP enabled interfaces<br>
br0 8000.0019b9e57ae5 no eth0 vnet0<br>
virbr0 8000.000000000000 yes <br>
<br>
Thank you again for any help,<br><font color="#888888">

run the command "qemu-syetm_x86 ttylinux.img" from the ttylinux image
directory..you can see a window and will start boot ttylinux...<br>
and asked password for recover from the disk failure after entering the
password "password" you just run the command "fsck /dev/hda1" it will
remove the error and properly shutdown the system by typing the command
halt or shutdown ....after the correct shutdown and close the window
...and try to run the ttylinux again and verify...is it ok then again
shutdown correctly and copy this ttylinux image for your cloud .....<br>

I'm trying to access through ssh to my instance of ttylinux VM created

with a similar problem, but also fsck on that VM doesn't help me to
solve the situation.<br>
<br>
Could it be related to the network configuration of my kvm host?</tt>
